I fabric frame a lot of mine. I just stitch on coordinating borders, layer a thin batting and backing, put right sides together with the batting on the bottom, turn, do a close edge stitch around it and either stitch a hanging sleeve on the back or put hanging tabs on while stitching the sandwich together. Less costly and I rather like the look, just an option for you.
Some people recommend not covering any fabric work of art with glass especially if you live in a humid area as mold can develop behind the glass.
